receiving openings of automobile radiator aprons.

are of circular shape and it has been customary to provide similarlyshaped closures for said openings, the closures being detachablyconnected to said aprons by rotary movement of said closures. In someinstances, said aprons have forwardly extending annular beads or ridgesaroundsaid openings, provided either for ornamental purposes orotherwise, and the closures have engaged said aprons just outside ofsaid beads or ridges, thereby becoming sort of interlocked therewith.-As a result of this interlocking and the necessity for rotating theclosure in applying and removing the same, said beads or ridges havebeen confined or limited to annular shapes.

It is therefore the general object of the present invention to providean improved closure for the openings of objects of the V sort abovementioned, which closure permits said objects to be provided around saidopen- "ings with forwardly extending beads or ridges of non-annularform, such as oval, the closure being nevertheless capable of detachableconnection to said objects by rotary movement of said closure.

A more specific object of the invention is the provision of an improvedclosure of the character described which consists primarily of twoparts, a cover part, preferably of ornamental character, and a lockingpart adapted to be detachably connected to the radiator apron or otherobject having the opening to be closed, said parts having a threadedconnection therebetween which prevents complete separation ordisassembly thereof but which permits movement ofthe cover part towardand from the locking part so that said cover part can be moved intoengagement with the radiator apron or other object after the lockingpart has been connected thereto and can be moved out of such engagementto enable rotary movement to be imparted to the locking part to discon-The openings to be closed in these aprons 1928.

nect it from said "radiator apron or other object. i L l 3 Furtherobjects of the invention are in part obvious and in part will appearmore in detail hereinafter. v

In the drawing, in which is illustrated one suitable embodiment of theinvention, Fig. 1 is a central vertical sectional view of the closuredetachably connected to the filler neck of an automobile radiator apronor other object; Fig. 2 is a similar view but showing the cover part ofthe closure separated from the locking part thereof so as to 7 enablethe closure to be rotated to remove it; Fig. 3 is a cross sectional viewof the closure on the lines 33, Figsrl and 2 Fig. 4 is a top plan viewof the closure; ig. 5 is a cross sectional View of the closure on theline 55, 2; Fig. 6 is a top plan view of the filler neck to which theclosure is adapted to be connected; and Fig. 7 isa vertical sectionalview thereof on the line 77, Fig. 6. Referring to said drawing, 1represents an automobile radiator apron or other object having anopening to be closed, a tubular neck 2 being suitably mounted insaidj'opening. Said neck is provided at its upper end with an inwardlyextending annular flange 3 substantially flush with theapron 1,-sa1dflange terminating in a depending flange 4. At two diametricallyopposite points, parts of flanges 3 and 4 are cut away to provide twopassageways 5 for the closure locking fingers, as will later appear. Thecutting away of said fiange parts provides two depending flange portions4 of substantially semi-circular form, and the lower edges ofsaid flangeportions are inclined to form two cam surfaces 6 with which the closurelocking gers cooperate in effecting a detachable connection therewith.Preferably and as shown, each cam surface is provided atits rear endwith a dwell or seat 7 to receive aclosure locking finger'when theclosure is in fully locked position on the filler neck, and each flangeportion 4 is'provided adjacent its dwell or seat with a dependingprojection 8 to limit rotary movement of the closure, as will be readilyunderstood. For purposes of 7 ornamentation or otherwise, the apron l'isprovided around said neck with a forwardly extending bead or ridge 10,which bead or ridge maybe of any suitable shape, annular ward and fromthe'other but which prevents complete separation or disassemblythereof.

The locking part includes a cup-shaped member having a cylindrical sideportion 15 and a circular bottom portion 16, said bottom portion beingprovided with a circular depression 17 forming a correspondingly shapedrecess. Suitably secured within said recess, such as by a crimpingoperation, is the circular base portion 18 of theclosure locking member,said base portion being provided with two diametrically opposed lockingfin- .gers 20 which extend upwardly'and outwardly through openings 21 inthe cylindrical side wall 15 of the cup-shaped member. The projectingends 22 of said fingers are adapted for cooperative engagement with thecam surfaces 6 of the filler-neck, as will later appear. "-Theupper endof the cylindrical side portion 1510f the cup-shaped member merges intoan outwardly extending annular flange 23 terminating in an upwardlyextending marginal portion 26. Seating upon said outwardly'extendingportion 23 is a diaphragm member 27 on which seats a disc 28'suitablyslotted or sheared to provide in the marginal portion thereof fourcircumferentially arranged upstanding arms 29. Said diaphragm member andsaid disc are maintained in such seated position by bending inwardly theupper end portion 32 of the marginal portion 26 of the cup-shapedmember, as clearly indicated in Figs. 1 and 2.

, The ornamental coverpart of the closure includes a top member having adome-shaped portion 35 and a depending skirt portion 36 bent inwardlyinto confining engagement with the depending marginal portion 37 of aplate member 38 substantially covering the bottom of the dome-shapedportion 35 of the top member. The central portion of said .plate memberis provided with four circumferentially arranged slots to receive theupstanding arms 29 of the locking part of the closure, said platememberbeing prevented from escaping from said arms by a disc 39 welded orotherwise permanently mounted upon the upper ends of said arms, whichends are provided with shoulders 40 upon which.

said'disc seats, as shown in Fig. 1.

The disc 39'is'provided with a central opening in which is threaded adepending stem provided at itsupper end with a suitable head 46 lyingwithin a central opening in the dome-shaped portion 35 of the topmember. Said head has secured thereon a suitable knob f? to which rotarymovement is imparted when it is desired to rotate the stem 45 to effectrelative movement of the cover and locking parts of the closure. Thelower end portion of said stem extends through a centrol opening in theplate member 38 and has secured on its lower end a lock ring 50 whichprevents the stemfrom being removed from the plate member 38 and thedisc 39.

To secure the closure to the radiator apron or otherobject 1, the coverand locking parts of the closure must be in separated relation, as shownin Fig. 2, which separation is effected by counter-clockwise rotationof'the threaded stem 45 through its knob 47. The projecting ends 22 ofthe fingers 20 of the closure locking part are then inserted through thepassage-ways 50f the filler neck, 7

after which clockwise rotary movement is imparted to said locking partto cause said finger portions to ride down the cam surfaces'6 until theyreachthe dwells 7 therein adjacent the stop projections 8/ The coverpart of the closure of course rotates with the locking part thereof, dueto the extension of the arms 29 through the plate member 38;.

After the closure locking part has been thus connected to said fillerneck, the closure cover part ismoved toward said locking part intoengagement or substantial engagement with the radiator apron or otherobject 1. Such movement is effected by rotating the threaded stem 45. ina clockwise direction,

the 'cover' part moving from the position ridge 10 of the apron 1. Afterthe cover n5 part has been thus separated from the locking part, bothparts are rotated in a counterclockwise direction, which causes thefinger portions 22 of the locking part to leave the dwells 7 and ridedown the cam surfaces 6 until they reach the passageways 5, at whichtime the closure can be readily removed from the filler neck, as will bereadily understood. If desired, and as shown, agasket 52 of cork orother yielding material may be interposed between the top flange 3 ofthe filler' neck and the outwardly extending flange 23 of the closurelocking part, said gasket effecting a tighter seal of the filler neckopening.

What I claim is: i l 1. A closure, comprising a locking part providedwith an outstanding arm and a cover part provided with a member having aslot through which said arm extends, means on the free end of said armfor preventing escape of said cover part member, said escape preventingmeans being provided with a threaded opening, and a threaded membercarried by said cover part and threaded in said opening, wherebyrotation of said threaded member causes said cover part to move withoutrotation toward or from said locln'ng part.

2. A closure, comprising a locking part provided with an outstanding armand a cover part provided with a member having a slot through which saidarm extends,means on the free end of said arm for preventing escape ofsaid cover part member, said escape preventing means being provided witha threaded opening, and a threaded member carried by said cover part andthreaded in said opening, whereby rotation of said threaded membercauses said cover part to move without rotation toward or from saidlocking part, and means carried by said threaded member for preventingits withdrawalfrom said threaded opening.
